Appointed as Chancellor of the Exchequer within just five years of becoming an MP, Rishi Sunak's rise has been rapid. He was parachuted into a safe seat for the Conservative party during the 2015 election and his trajectory has been skywards ever since. However, he takes office under difficult circumstances, the post only became vacant as former Chancellor Sajid Javid rejected the prime minister's order to fire his team of aides, saying "no self-respecting minister" could accept such a condition. So can Rishi Sunak take the helm and will he stand up to the Prime Minister?
